Ensure all AppArmor Profiles are in enforce or complain mode

中レベル 1自動ros

説明

AppArmor profiles define what resources applications are able to access. The audit runs apparmor_status and requires loaded profiles (enforce or complain) and no unconfined processes that have a profile. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

チェック方法

監査方法: シェルコマンド

shell

out=$(apparmor_status 2>/dev/null) || exit 1
l=$(printf '%s\n' "$out" | awk '/profiles are loaded/{print $1; exit}')
u=$(printf '%s\n' "$out" | awk '/processes are unconfined/{print $1; exit}')
[ "${l:-0}" -gt 0 ] || { echo 'no AppArmor profiles loaded'; exit 1; }
[ "${u:-0}" -eq 0 ] && echo compliant || echo "$u processes are unconfined"

期待される出力: compliant

Run the following command to set all profiles to enforce mode: # aa-enforce /etc/apparmor.d/* OR Run the following command to set all profiles to complain mode: # aa-complain /etc/apparmor.d/* Any unconfined processes may need to have a profile created or activated for them and then be restarted.
